Question
Surface Blends
Hello,
I'm stuck on this wretched dome again!
I have a thin plastic dome - think of one of those white hard hats construction workers wear. All over the head part, it is nominally 5mm thick. Around the base, where it grazes the ears, it has a 50mm wide flange. The flange is at 45 degrees to the dome (so it partly covers the ears and partly obscures the vision). The flange is 15mm thick. The dome blends down to its nominal 5mm from the 15mm at the flange over a distance of 50mm.
I only have the data defining the outer surface of the dome/flange complete. I have modelled the inner surface of the head/dome by offsetting the outer surface by 5mm and the inner surface of the flange by offsetting the outer surface by 15mm.
I have then cut out the flange surface to leave the outline of the dome surface and cut off the outer edge of the dome surface to match the outline of the flange. They are modelled as surfaces, not solids. I therefore end up with two surface features, nestling one inside the other, with a 10mm gap between them around the flange/dome join.
Now I need to blend the two surfaces together.
I can't get Pro/E to do the blend.
I thought I could insert a blend, surface. project sec and select the two surfaces to blend between.
I get all the way through until the last few clicks, when I try to select the surfaces of the flange and of the dome and Pro/E decides that neither of them is a surface. I am left with the option of quitting out and starting again.
I am sorry, I can't attach the part, as it is confidential.
Have I explained it clearly enough to make sense? If so, have you any suggestions for alternative methods, or where I am going wrong with this one?
Thanks,
John
